A popular new trend in nutrition science promises a quick answer to dietary problems. A product called Pinnertest, and a handful of others like it, appear to have the backing of a lot of celebrities with their claims.

They claim their mail-in blood test can help you know which foods you are intolerant to.

News 3 reached out to Pinnertest after seeing how many reality stars and independent filmmakers were featured in their marketing. Pinnertest’s sell is simple: a couple drops of blood helps labs figure out for you how to avoid a variety of foods that may be causing you problems.

Those who buy the test may be after slimmer, sexier bodies and better health.

Pinnertest’s lab claims to help you know which foods to eliminate from your diet.

Company spokesperson Patricia Costa says interest in the test is growing big time.

“It’s definitely become big, a lot of people are finding out about us,” said Costa. “We get emails on daily basis changed their lives.”

Costa says following the results of the test, along with a healthy diet and exercise, can help test-takers to avoid weight gain and bloating, psoriasis, and other conditions.

Pinnertest’s marketing features celebrities promoting the product.

News 3’s Reed Cowan took the test, which returned, showing intolerances to wheat, lentils, and onions.

Pinnertest provided News 3 the test for free so we could investigate the tests’ claims.

Others pay $490. Costa says Pinnertest tries to help people manage the expense.

“Based on the research, I’m not seeing that they’re very accurate,” said Canyon. “The Pinnertest doesn’t test for Immunoglobulin A which is another antibody. You’re getting only a fraction. Only tests for Immunoglobulin G.”

Pinnertest told News 3 their test’s results are based on the immunoglobulin which manifests food intolerances.

Pinnertest defends the science behind their tests saying:

“It is costly, but it’s easy to use gives results and the answers you want to know.”

Las Vegas Dr. Dahlia Wachs says, while she was skeptical at first, she’s not opposed to the tests.

“The average elimination diet to see what you are intolerant to takes two months and that is why we have a consumer drive for these kind of things … bam … results in two days,” said Wachs. “If they spend this kind of money on a test … it’s amazing and suddenly they’re compliant with things I told them before, so I say if you have the money, go ahead and take the test.”
